Carl Sagan’s Cosmos E12 – Encyclopaedia Galactica

There must be other civilizations in the immensity of the cosmos, more advanced and older than ours. With UFOs (Unidentified Flying Objects) and other close encounters disproved in favor of communication through SETI (Search for Extraterrestrial Intelligence) and radio telescope such as Arecibo observatory. Questions are elevated about the search for more insightful life away from the earth. By the use of the Drake equation, the probability of the existence of technically advanced civilization somewhere else in the galaxy is disrupted, and a hypothetical future Encyclopedia Galactica is debated as an information depository about other worlds in the Milky Way. While referring to the META scanning the skies for signals, the cosmos update remarks that there have been less revealing of UFOs and more stories of Alien Abductions.
